Performance issues directly impact user engagement and conversion rates.
https://costdown.org/: 474ms CPU time
Informational: CPU time spent on this resource. Total >1s is a perf budget violation.
Both www and non-www versions serve content
Serving both www and non-www splits SEO signals between two URLs and creates session-cookie scope confusion.
Heading level skipped: H1 → H3 (missing H2)
Skipping heading levels breaks the document outline — screen-reader users lose track of section nesting.
Registrar lock is NOT enabled
Without registrar lock, an attacker who phishes your registrar credentials can transfer the domain in minutes — total brand hijack.

Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.
Conversion barriers
2 barrier(s) likely increasing bounce by ~10%.
- Page loads in 2.9sEvery additional 100ms above 2.5s costs conversions — you're 404ms over→ Target <2.5s LCP: defer non-critical scripts and optimize the hero image
- Content is hard to readGraduate-level reading difficulty — limits the addressable audience for product or blog pages→ Shorten sentences; replace jargon with plain language; target Flesch ease ≥60

No build tool detected
A framework (Google Search Console) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.
Complex technology stack detected
12 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
